Angles can be measured in radians or degrees. The Angular Unit Node can be used to convert from one system to the other.

In mathematics there are two methods with which angles can be measures. The most commonly used method is in degrees, e.g., between 0° and 360°.

In mathematics, the relationship within a circle or circle section can be defined even more flexibly using radian angles. An angle of 90° translates to π/2. Consequently, 180° is exactly π and 360° is 2* π. Since Cinema 4D also calculates internally using radians, it might be necessary to manually convert a calculation to another system. This can be done using this Node.
